. T all whom t may concern.'

' contemplates the provision ofapair of ro ta Be it known that I, LANDoC. KAsArrM, a citizen ofthe United States, and resident of Laporte,inthe county of Laporte and State of Indiana, havev invented certain newandl useful Improvements in Street-Indicators for Cars, of whiclispecification. Thisv invention 'has Vreference generally to thefollowing isa indicators and more particularly relates vto a streetindicator especially adapted for use on street cars.

Itisthe primaryV aim -and' object yo th1s invention toprovide a housingadapted to,

be mounted in' the 'front part of a; street car for operativelylreceiving novel street indicating means, means being alsomountedin thehousing and in connection withk the street indicatingmeans forVoperating; theV indicating means soA as to successively disating'meansvso as to consequently insure .an

elicient operation of theu indicating means. lMore speciiically, thepresent invention tably mounted rollers for receiving .the indicatingweb aswell as another roller fric'- tionally engageable with theintermediate portion 'of the web for moving ,the web from one rollertothe other, manually operable means Ybeing incidentally arranged inlconnection with the yroller .for partially rotating the operatingroller a predeter- `mined'distance 1 f Still furthe'nthe invention Yhasto. provide' means for holding the web in frictional en-l gagement withthe operating roller to cilitate the movement 'of the web.

Among the otherV aimsand objects ofthe present invention may berecitedthe provision of a device of the charactermentioned with aviewtocompactne'ss and in which the number of parts are few, the con!connection withv they accompanying drawings forming a part thereof,wherein I disc lose a Apreferred embodiment of the' invention forthepurpose of illustration.

Theinvention is .clearly illustrated in the' accompanying drawings inwhich:

Figure 1 is a longitudinal section throughv the housing showing theinvention proper in side elevation.

Fig. 2 a horizontal section through the housing showingthe inventionproperl in top plan.

F ig. 3 isa side elevational detail of the controlling means for theVoperating roller.

` Similar characters ofA reference are employed in all of the abovedescribed views,

to indicate corresponding parts.

Referringnow, more particularly, to the accompanying"y drawings, Iprovide a housing l, which may be and preferably is of a rectangularconfiguration being provided with a sight-opening 2, in the front endthereof. This housing is adapted to be mounted in the Jfront end of acar in such a position as to be within the view of the passengers.`Mounted adjacent top and bottom of the housing and transversely of thesides are a pair of shafts 3, while rollers 4 and 5, are rotatablymounted on the shafts the upper roller 5 having a resilient action for apurpose that will presently appear. An indicating web 6.V is connectedto the `lower roller 4 at one end while the opposite'end is connected tothe roller 5. This web asis apparent upon reference to the drawing iswindable about the rollers and is also provided throughout its lengthand transversely thereof with'the names Aof streets in the order 'inwhich the car approaches them. i

tion of the` web directly behind the sight opening. 2 and valsotoprovide means for operating or moving the web Vfrom the roller 4 to.'the rollerv 5, I have rotatably mounted another shaft 7 transversely ofythe housing and' in the sides thereof adjacent the forward end'.vAlarge roller 8, is carried by `this shaftjand is maintained infrictional engagement withy the inner or rear vsurfaceof the web andwhen the roller S' is partially rotated the web will be moved a shortdistance ina corresponding direction. Friction rollers 9, are rotatablymountedl in suitable brackets 10,. above and below the sight 2 andtransversely of the housing the rollers being arranged to hold llll/'1thv a View toward maintaining a por-V 4o e .that the pawl willengage the tooth in the the web in Yfrictional-relation with the rollerV8 and facilitate the Vefficient operationv thereof. Y

In order to manually actuate the roller 8 at a predetermined time so asto successively displayY the names ofthe streets through the Vsightopening, I have mounted a bracket 11,

on the under surface of the bottom. A lever 12, is fulcrumedintermediate itsrendsI to ythe' lower' end Vof Ythe bracket .11. while acoill spring` 13, has its respective ends con` lnected to one .end ofthe .lever 121andv to 'the bottom of .the housing Vfor a purposethatwill presently appear.y .A .rod 14, has. vits lower end Apivotallyconnected tothe .op-

able fastening device 17, to the upper end of the rodllf while a pawl18,'is also vpivtrained about'zan idler 22, and run to a suitotallyconnected to the upper end ofthe rod von 4the side opposite to that uponwhich the arm 1s arranged while connection is maintainedthrough thefastening device 17. `A

ratchet wheel 19, is rigidly. mounted on .theV shaft adjacent the roller8 while ythe pawlf 'is' yieldingly Vheld in engagement with the teeth ofthe ratchet wheel by means of az spring 20, connected to the rod 14. Acable.

21, `is connected to the end of .the lever 12 to which the .spring 13 isconnected and is able lpoint on the` car (not shown) :where it can beconveniently pulled by the conductor to move the lever.l2 againstr thetension of..

the spring and consequently raise. the; rod -sol ratchetwheelA above.the one l'in which it is i positioned whereuponV the cableyis releasedand the tensionfofithe spring 13y consequently movesthe ratchet wheel aswellas the shaft and roller 8 so as to mo-vge the web v and'display thenext street thereon through Vthe sight opening.` e 1'* For the purposeof controlling themove- .ment of'theoperating rollerv Sso astopreventthe. roller from moving.i beyonda pr`e V .f determined distance andthereby insuring an effective voperation of the indicating web I haveconnected a support 23, to the housing while van arm24, is pivotallyconnected tfOjV "the gouter end thereof. Azroller 25,"is rol r tatablymountedron the outer, end yofthe arm 24and is yieldably held inengagement with a spur wheel 26,fcairied' by the shaft 7, Aby means ofa. spring 27,. the respective endsrof which are connected to. thesupport ij 23 and the arm 24.] It will'l be noted that Vthere are' thesamenumber of teeth on the Y wheel 26.',as `there are onv the ratchetwheel 19 so that when the ratchet wheel is moved the distance of onetooth by the ratchet it .wil'l'fbe preventedv from moving farther by theroller 25 which is 'yieldably held in engagement withthe teeth on thespur wheel. This engagement of the roller' 25 with the tooth. of thewheelr26 however, isnotsuff.-v

ciently strong to prevent 'thev roller being moved a predetermineddistance by the operating means therefor. A

The. operation of he imma@ mtyte reviewed as followsz-V Assuming thatthe car.in wliich the `de- I Vice is. mountedhas started on itsroute'and'" thatithe major portion ofthe .web is'wound aboutthe roller 4the vconductor will'pull the'cable againstthe tension of the spring'v 13androck the lever 12 which moves the be'...engage' dv on thet'o'cthabovethe onei'n` i which it is engaged whereuponfthe'cable' is released:andthe spring 13 exerts its tension and moves theroddownwardlywhichrai'ses thepawl to partially rotate the shaft 7 i VIn- Y asmuch asthe roller .8 is carried by this shaft Zand frictionally associated withthe web. v6

the web will be moveda slightdistance so as to displaythe'properstreetthrough the sightropening `2 and thus; indicate .to the passengerswithin the car the name of the s treetfat lwhich the car willmalre itsnext stop, ifnecess'ary. The-spring roller 5 will automatically wind.theV web as the" slack oc-` curs in the web. between theroller and theroller .8. The spring pressed roller 25 engaged in thes'pur wheel26fallows the shaft to move only .ja` predetermineddistante. Soastdnsurethe efficient Operatieflof the indicating web."V V As is readilyapparent the,`

device can beY subsequently actuated ,inV a similar manner'tosuccessively ldisplay .the

`Vnames: of the streets inftrhe ordery inlvwhich theyareapproachedjbythe car. .if e Y Sincemany hangescould'be madei-n the,aboveV construction and many apparently widely vdifferentembodimentsjof this invention. could' be madewithoutdepartingfrom thescope Y. thereof, it is intendedv that' all matter contained 'inVthefabove description Yor shown in 'the"accompanying drawings shall. be.interpreted e asV illustrative.
